After speaking with a local bank mortgage lender (I have 3 more meetings scheduled with 3 other local banks), he determines my credit score is too low (under 600, not from bad debt, but thin layer/little credit usage history).

Just needed to change the filter which is recommended every 30-60 days depending on your usage.

I should probably be downvoted for saying this, but the reality is in most (if not all states) the courts are really looking for violations to security deposits, inappropriate living conditions, illegal stacking.  

They have the right to evict home owners for anything they deem inappropriate.

I was wondering if it's possible to call the gas provider and get a statement of the prior few years gas usage so I can estimate the bills that I would have to pay if I buy it.

In 1998, the current owner installed baseboard heating to accurately divide the cost/usage between tenants.  

You can't mess with water usage unless you have a big leak or leave a hose on.

. $120 usage I am slowly working to pay those down.

All different prices, two similar GRMs and one different that indicated greater appreciation.Can the GRM be used to tell me (quickly & easily) if I'm currently looking at properties in a market w/ a higher appreciation or if I'm looking at a market with lesser appreciation and higher cash flow.Is this a viable usage of the GRM as well?

During that time I have all rights of usage, I could sell the property to another foreigner who would assume the trust on the property or to a Mexican that would be able to own the property in fee simple.
